The TC654 has two (2) inputs for measuring fan RPM and +one (1) PWM output which can be used for fan control. + +Configuration Notes +------------------- +Ordinarily the pwm1_mode ABI is used for controlling the pwm output +mode. However, for this chip the output is always pwm, and the +pwm1_mode determines if the pwm output is controlled via the pwm1 value +or via the Vin analog input. + + +Setting pwm1_mode to 1 will cause the pwm output to be driven based on +the pwm1 value. Setting pwm1_mode to 0 will cause the pwm output to be +driven based on the Vin input. |
